The appearances of nonvascular lesions were as the following : solitary, huge cystic lesions with wall and septa obvious enhancement were found in malignant enbryonal sarcoma; mixed density mass with necrotic cystic change and solid portion enhanced obviously in carcinosarcoma; intrahepatic huge low density, cystic changes, calcification and margin enhancement were found in leiomyosarcoma.

血管源性表现为肝内多发低密度灶，强化明显，非血管源性表现为肝内巨大单发囊性病灶，增强囊壁和分隔明显强化；癌肉瘤表现为混杂密度肿块伴有坏死囊变，增强实质部分强化；平滑肌肉瘤表现为肝内巨大低密度病灶，可伴有囊变及钙化，增强见边缘强化。

Methods:By using transmission electron microscope and immunohistochemical technique,oncosis and TSP 1 expression in 57 cases of gastric adenocarcinoma were determined,and the interrelationship between them was studied.

血管形成在实体肿瘤的生长、浸润、转移中起着重要作用，凝血酶敏感蛋白1(thrombospondin1，TSP1)是一种有效的血管形成抑制因子，目前尚未见关于TSP1在胃腺癌中的作用报道。

Off-label use was defined as use in restenotic lesions, lesions in a bypass graft, left main coronary artery disease, or ostial, bifurcated, or totally occluded lesions, as well as use in patients with a reference-vessel diameter of less than 2.5 mm or greater than 3.75 mm or a lesion length of more than 30 mm.

非适应症应用定义为支架应用于再狭窄病变、旁路移植血管病变、左主干病变、开口病变、分叉病变、完全性闭塞病变以及支架应用于靶血管参考直径小于2.5mm或大于3.75mm或病变长度大于30mm的患者。

In the cardiovascular system, the endogenous NO, CO, and H2S form three specific and relevant pathways with their corresponding enzymes including nitric oxide syntheses, the home oxygenize and cystathionine-r-lyric enzyme, whose affect can relieve the atherosclerosis.

血管系统中内源性气体信号分子NO、CO、H2S作为一种独特的血管活性物质，分别与其相应的合成酶一氧化氮合酶、血红素加氧酶和胱硫醚－r-裂解酶形成独立而又相互关联的体内重要抗氧化系统，可以减少动脉粥样硬化的严重度。

Result: The divided functional recipes of DHZCP could significantly decreased the deposit of lipid and the atherosclerotic plaque area in aorta intima, relieve the histopathological changes of atherosclerosis,and inhibited the proliferation of vascular smooth muscle cells and collagen to reduce pachynsis of vascular intima. The divided functional recipes of DHZCP also reduced IT, IMT and IT/MT and reversed the contractive vascular remodeling.
